I'd love to see a cost per KW-H for generating electricity w/ a genset run w/ a VW diesel. I mean total cost, to include the
generator, fuel, oil, maintenance, etc. All I know is that I took the specs from a couple portable generators and got a rough estimate
based on the fuel usage at max output. It was much more expensive than line power. I do not think you could even come close to the
power plant's efficiencies of scale.
